Various exemplary methods, systems, and devices for joint to pump elevation level user interfaces, autocalibration for joint elevation, and joint pressure estimation are provided. In general, an arthroscopic pump can be configured to estimate fluid pressure at a surgical site, e.g., at a joint, to provide an accurate indication of fluid pressure to users. In an exemplary embodiment, the fluid pressure estimation is based on a fluid pressure measurement at the pump that is adjusted at the pump, e.g., by a processor at the pump that executes instructions stored in a memory at the pump, using one or more control algorithms that adjust for one or more factors, such as pressure loss in tubing and sheath through which fluid flows between the pump and the surgical site and elevation difference between the pump and the surgical site.

A refrigerant management system controls the supply of refrigerant from two or more variable speed and fixed speed compressors to a plurality of cryogenic refrigerators. The system employs a plurality of sensors to monitor and regulate the overall refrigerant supply to deliver an appropriate refrigerant supply to each of the cryogenic refrigerators. The amount of refrigerant to supply is based on an aggregate demand for refrigerant from the plurality of cryogenic refrigerators and a refrigerant correction metric. An appropriate supply of refrigerant is distributed to each cryogenic refrigerator by adjusting the speed of the variable speed compressors or, alternatively, selectively turning the compressors on or off. The speed of the variable speed compressors is adjusted by determining an amount of refrigerant to supply to the plurality of cryogenic refrigerators. If the aggregate demand for refrigerant exceeds the capacity of the compressors, then the speed of a refrigerator within the plurality of refrigerators is adjusted.

A vacuum network control system includes a plurality of nodes configured for control over operational processes of the system. The plural nodes are configured, in a network ring or other topology, as a selectable master node for controlling the operational processes. Control can be distributed among, and passed between, each of the nodes. Each node on the network monitors adjacent network connectors to detect a fault in the network. In response to a detected fault, a disconnect is mapped to the fault, and the network topology is reconfigured for continued communication among the nodes and with external devices.
